CesiumAstro has secured $470 million in Series C growth funding to accelerate U.S. expansion and scale production of its space and defense communications platforms.
How Will CesiumAstro Use the Series C Fund?
CesiumAstro said Monday the new funding will support growth initiatives planned for 2026, including expanded manufacturing capacity; faster deployment of its software-defined, artificial intelligence-enabled communications systems; and the construction of a new 270,000-square-foot headquarters facility in Texas.
The company expects the site to consolidate design, assembly, integration and testing functions into a single U.S.-based operation, with operations projected to begin in early 2027. CesiumAstro is scaling production of Element, its fully integrated low Earth orbit satellite platform, while growing technical and program teams to meet rising government and commercial demand for resilient space-based connectivity. The company has projected that the effort will generate more than $500 million in investment over five years and create more than 500 high-skilled jobs in Texas.
The Series C funding round includes $270 million in equity led by Trousdale Ventures, with participation from Woven Capital, Janus Henderson Investors, Airbus Ventures and the Development Bank of Japan. The financing also incorporates a $200 million package backed by the Export-Import Bank of the United States and J.P. Morgan under EXIM’s “Make More In America” initiative.
How Does Series C Build on Earlier Investment Momentum?
“We’ve backed the company across multiple rounds because this team isn’t chasing headlines—they’re building a forever company,” said Phillip Sarofim, founder of Trousdale Ventures. “Over the past year alone, CesiumAstro moved from announcing its first fully integrated satellite to securing eight SpaceX rideshare launches, accelerating on-orbit validation. Their momentum and maturity set them apart.”
The Series C round marks the latest step in CesiumAstro’s growth trajectory, following its $65 million Series B+ raise in 2024, also led by Trousdale Ventures and backed by strategic and institutional partners to expand research and development and manufacturing capacity.
